Deferred publication in Drupal 8

Install module Scheduler:

composer require drupal/scheduler ; drush en scheduler -y

In the material type settings, check the "Allow this material type to be scheduled for publication.

When adding/editing material, a delayed publication time field will appear in the sidebar:

Specify the time of the future publication, save it. The material will have the status "Unpublished" and will change it to "Published" on the specified date.

The news will be published at the scheduled time only after the cron is started.
Running the standard cron every minute is not required. The Scheduler module provides a light version.

In the settings of the Scheduler module, go to the Lightweight cron tab:

/admin/config/content/scheduler/cron

Copy the first or second line:

wget -q -O /dev/null "https://tester.ru/scheduler/cron/eeweequeo7ko2auyeengo"

Add this command to the scheduler on your server:

Save, check, use!
